Undead Invasion

Undead Invasion is a roguelike endless zombie survival game where every run pushes your reflexes, strategy, and adaptability to the limit. You face escalating waves of undead enemies, build defensive setups, purchase weapons and upgrades between rounds, and try to survive as long as possible.

The core tension comes from permadeath. Once you die, your progress resets completely. Every attempt becomes a fresh challenge, forcing you to rethink your strategy and improve your decision-making.

With bloody pixel combat, expanding zombie hordes, and a massive selection of weapons and traps, Undead Invasion delivers high-pressure survival action from start to finish. Jump into the chaos and play Undead Invasion now on AntGames to test how long you can survive.

How to Play Undead Invasion?

The gameplay follows a day-by-day progression system. Each new day increases enemy count, difficulty, and battlefield pressure.

Your main objectives are:

• Survive each zombie wave
• Earn money from kills
• Buy upgrades and equipment
• Prepare your loadout
• Repeat until overwhelmed

The longer you survive, the more intense and chaotic the battlefield becomes.

How Does Day Progression Work in Undead Invasion?

Early Days

• Day 1: One zombie - basic movement and attack practice
• Day 2: Two zombies - spacing becomes important
• Day 3: Three zombies - overlapping attack timing

Later Days

• More zombies spawn per wave
• Enemies move faster
• Zombies gain more health
• Mistakes become increasingly punishing

Difficulty scales exponentially, not linearly.

How to Buy Upgrades Between Waves?

After each day, you receive cash based on:

• Total kills
• Survival duration

You may purchase up to three items before starting the next wave.

Available Upgrade Categories

Training Upgrades

• Speed
• Strength
• Kick Training

Support Items

• First Aid Pack
• Banana

Weapons

• Crowbar
• M1911
• Glock 17
• Assault weapons and more

Defense Tools

Early purchasing decisions strongly influence how long your run will last.

How to Prepare Your Loadout?

Before beginning the next wave, you must select:

• Primary firearm
• Secondary firearm
• Melee weapon
• Armor or survivor suit

The game reminds you clearly:\ Death = losing everything. If permadeath feels too intense, Playground Mode offers a lower-pressure alternative.

How to Control in Undead Invasion?

The controls are intuitive, allowing you to focus on survival:

• W / A / S / D: Move
• Left / Right Mouse Button: Shoot
• R: Reload
• Q: Switch weapon
• E: Melee attack
• 1to 9: Use item slots
• Space: Kick
• Tab: Start next wave

Efficient weapon switching and movement are critical for advanced survival.

What Makes Undead Invasion Stand Out?

• Roguelike permadeath tension
• Endless scaling difficulty
• Day-based progression
• Flexible loadout customization
• Defensive building mechanics
• Global leaderboard ranking

Each run feels unique due to varying weapon choices, trap setups, and zombie density.

What Are Top Survival Tips for Undead Invasion?
